Web12 sep. 2024 · Because the same number of field lines crosses both S 1 and S 2, the fluxes through both surfaces must be the same. The flux through S 2 is therefore Φ = E A 1 = E A 2 c o s θ. Designating n ^ 2 as a unit vector normal to S 2 (see Figure 6.2. 2 b ), we obtain (6.2.1) Φ = E → ⋅ n ^ 2 A 2. Note Web5 nov. 2024 · 17.1: Flux of the Electric Field. Gauss’ Law makes use of the concept of “flux”. Flux is always defined based on: A surface. A vector field (e.g. the electric field). and can be thought of as a measure of the number of field lines from the vector field that cross the given surface. For that reason, one usually refers to the “flux of the ...

WebInside a magnet or a piece of magnetised material, the flux just follows the direction of magnetisation. It emerges from, and enters into, the iron at the poles. So start sketching at the poles, all flux lines are continuous. A line which emerges (conventionally at a north pole) enters the material again at the south pole. Flux lines never cross.
